This is very interesting - I was wondering about this too. Assumed it was too high to be reasonable but guess I'm wrong. The question is: what's the cost vs acquiring the same qty of $ by being a good citizen. I suppose first you need to have a lot of crypto to double spend it.
you can't easily make a million from a single dollar that you can double spend. having lots of crypto surely helps reduce the time it takes to satisfy your greed.
